Astronomers say they have discovered a distant planetary system with planets arranged in a surprising order, challenging long-standing ideas about how planets form. In our Solar System, the four ...

ALMA, located in the Chilean Atacama desert, is the most powerful telescope for observing the cool Universe — molecular gas and dust. ALMA studies the building blocks of stars, planetary systems, ...

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we're not as familiar with. Scientists think they understand how the most important moon ...

New work offers fresh evidence supporting the supernova shock wave theory of our solar system’s origin. According to one longstanding theory, our Solar System’s formation was triggered by a shock wave ...

A research team led by University of Minnesota School of Physics and Astronomy Professor Yong-Zhong Qian uses new models and evidence from meteorites to show that a low-mass supernova triggered the ...
